Cryptocurrency exchange Binance confirmed on Thursday that a massive security breach affected an estimated $6.3 billion in assets, potentially establishing the incident as the largest digital asset heist in history. The unprecedented breach at the world's largest cryptocurrency platform immediately triggered containment efforts by the exchange alongside investigations by blockchain intelligence organizations.

Binance estimated the impact of a security incident at $6.3 billion, with around $3 billion in crypto assets frozen, and pledged to cover all losses.

Financial estimates regarding the scale of the exploit varied slightly among reporting sources, with some analysts evaluating the total impact at approximately $6.4 billion, or roughly 8.4 trillion won. Despite the massive valuation of the affected holdings, the exchange successfully intervened to neutralize a portion of the damage by freezing about $3 billion in digital funds while actively working to contain the broader fallout.
